MUT (Media Utility Tool) open testing

[Jesse]

Hi Lobster,

When Mut shows you a "close" button for your cdrom, it thinks that the tray is ejected, so mut provides a way to close it.
I'm pretty sure that the cause of thinking that it is open is a bug in the kernel module that I'm asking "where is the tray?", it is saying "the tray is open".
The "No Disk" or "No media" makes sense when the tray is closed, and when mut is told that it is closed, mut shows an "Eject" button.
I don't think any cdrom drive can tell the moment you place a disk on the tray before closing it...

Hi Mathiasdm and Rich,

Sorry about accessing your printers
Can you please run mut with the mut-debug script, and then send me the generated output log file.

The mut-debug-output.txt file is always next to the mut.tcl program file, i.e. in the same directory.

Lets make mut work for your puppies too

Yep. When I restarted the computer and opened MUT again, the printer started making noise again. It's an HP Deskjet 695C.

Deskjet 815c does this too.......doesn't print anything, it just initialises, then takes a sheet of paper part way in, then the error light on the printer flashes !
don't know why?
( if it helps with anything, it's a parallel port printer )

That's exactly what mine does too.

Kinda funny, actually
I'll run the debug script as soon as I can (I'm on Windows right now, kinda hard.).

Isn't there some kind of language censoring on this forum........

Okay, I've used mut-debug. Here's the output (.txt-files are not allowed as upload-file):

No comment on that one

[Jesse]

Hi Mathiasdm,

Your log file looks very healthy, you did have your printer plugged in at the time I hope!

Ok, so the fix should be very straight forward, the problem is very likely to be with when Mut loads the Kernel modules, probably just a kernel module that applies to your printer is what is triggering the odd behaviour.

Can you please edit the mut-0.0.5.rc3/bin/load_drivers.sh file, and firstly comment out all the 'modprobe ...' lines, I suspect that the last two in the file might be the offending ones. Try rebooting and running mut with more and more modproble lines in load_drivers.sh uncommented, until you find out which one accesses your printer, and causes the problem.
I've put comments in load_drivers.sh which might help you locate the problem faster.

Please let us know how it goes.

Jesse

[Rich]

Commenting out the Iomega Zip drive ( modprobe imm ) fixes this printer problem on my system.

Hope this helps

[Jesse]

Heh, and here I was thinking that was the usb zip disk module... oops!

Does anyone have a usb zip disk they can try Mut with?

Jesse

[Guest]

Running RC3 under puppy 1.0.3.

I get an odd error message: "::img::img(fd0)" can't be found. I can provide more details if needed.

At first I though it was a missing icon path - that I was running MUT from the wrong directory. However, my Puppy system doesn't have a floppy drive either. Missing mount point, perhaps?

[BarryK]

Puppy 1.0.4 has MUT 0.0.5rc3, renamed to 0.0.5.
The imm module is disabled.

[Guest]

I hope someone is still checking this thread...
how does one get MUT to load two floppy drives?

[Jesse]

Hi,

Floppy disks are a bit archaic on the 2.4 kernel, you can't easily detect them in a nice way. i.e. if they are not there, MUT would lockup for a long period.

To give yourself an access point to the second floppy disk "fd1"
edit the script file /usr/lib/mut-0.0.7b/mut.tcl
about line 363 you will see this:

if {$::majorBusRev(fd) >= 0} {
set ::diskStats(fd0) "$::majorBusRev(fd).0.fd.floppy"
if {$::debug} {puts "set ::diskStats([lindex $line 2]) $::diskStats([lindex $line 2])"}
}


change it to look like this for second floppy drive:

if {$::majorBusRev(fd) >= 0} {
set ::diskStats(fd0) "$::majorBusRev(fd).0.fd.floppy"
if {$::debug} {puts "set ::diskStats(fd0) $::diskStats(fd0)"}
set ::diskStats(fd1) "$::majorBusRev(fd).1.fd.floppy"
if {$::debug} {puts "set ::diskStats(fd1) $::diskStats(fd1)"}
}

Hi Jesse,
Did you get the p.m. I sent you awhile back ...at least a month ago I think.
Regarding improvements needed to get MUT working properly on puppy2.
Also, one of the bugs applies to puppy1 also -- usb drives formatted as "superfloppies" do not work in MUT.

And another:
I just answered another thread, someone mounted a floppy, and all filenames were truncated to 8.3 format. A msdos floppy can be mounted as vfat to fix this.

[HaJo]

Some USB devices take ages to initialise, like 25-30 seconds, during this time MUT can look like it has locked up.

Is there a "working..." message ?

I noticed (in Puppy 1-0-8r1) that MUT has a startup-delay of 4-8 seconds,
from the moment the icon is clicked until the MUT-window appears.
It would be nice to have a faster response (e.g. just an empty window
with a message "scanning devices").

Or maybe the windowmanager should display a "Busy" cursor.
As it is now, it looks as if nothing had happend for several long seconds...

[BarryK]

I'm getting around that in latest puppy2 by always loading usb-storage driver
at bootup.
There are reasons not to do that at bootup, one is that it slows boot-time, as have
to wait for it to complete, else kernel can crash.
However, I'm now loading it in the background after X has started.

[Jesse]

Hi Barry, Yes I got the PM, and have started looking into it.
The trickiest part is getting it to handle the superfloppies correctly.
I am looking into getting that working right, but I need to brush up on my tcl skills, its been a while
I hope to have an update for you in April.
I think that MUT only mounts vfat, as 'vfat' is used where 'msdos' would have been identified, MUT identifies a filesystem using its guess_fstype program.

I am shifting home at the moment, and will have a few weeks without internet, so I will likely find some time to get on top of this for you.

Hi HaJo, yes there are a few short delays, but I think they come from identifing cdrom drives, which takes a little time, unfortunately tcl does not appear to be able to offer a way around kernel functions that take several seconds to execute... one day when I rewrite it in C, I can work around that.
